DETAILED DESCRIPTION OF EMBODIMENTS

[0029] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, illustrative embodiments will be described in detail in this application with reference to the accompanying drawings.

[0030] In an illustrative embodiment of the present disclosure, a method for activating an MCU chip is provided, the method is applied to a first smart device having a Wi-Fi module. As shown in FIG. 1, the method includes the following steps.

[0031] In step 101, a wireless message is received transmitted from the second smart device when the Wi-Fi wireless authenticity chip is in a low power mode, the wireless message is for a low power mode.

[0032] In step 102, it is detected whether the wireless message is a predetermined activation message.

[0033] In step 103, if it is detected that the wireless message is a predetermined activation message, an interrupt activation signal is sent to the MCU via the activation terminal connected between the Wi-Fi chip and the MCU, in order to activate the MCU.

[0034] In this embodiment, the MCU chip and the Wi-Fi chip are integrated in the same Wi-Fi module.

[0035] In embodiments of the present disclosure, each of the first smart device and the second smart device can be a terminal device, such as a mobile phone, tablet, etc., and can also be an intelligent wearable device, smart home electronic equipment, etc. which is not limited in this application.

[0036] In the present embodiment, in the low power consumption mode of the first smart device, the MCU in the Wi-Fi module enters a standby state with the maximum reduction in power consumption, and the Wi-Fi chip in the Wi-Fi module also enters the low power consumption mode.

[0037] In particular, the Wi-Fi chip can only receive wireless messages with a low speed and small data size, i.e. wireless messages designed for low power mode, low power mode.

[0038] Since the Wi-Fi module consumes a lot of power, the smart device will control the MCU chip in the Wi-Fi module to enter the standby state with the maximum reduction in power consumption, if the Wi-Fi module does not have the task of receiving and transmitting data in order to reduce power consumption and save energy. When there is business logic to execute, the MCU is activated through an interrupt event in order to enter an operational state. If the smart device controls the MCU to enter the standby state with the lowest possible power consumption, other smart devices cannot receive data from the local smart device and transmit data to it until the MCU is activated and broadcasts the notification to other smart devices to notify them that the MCU itself has already been activated.

[0039] With embodiments of the present invention, when another smart device needs to receive or transmit data, it notifies the local Wi-Fi chip by transmitting the activation message remotely so that the Wi-Fi chip can activate the MCU via the activation pin, connected between the Wi-Fi chip and the MCU chip, thus improving the efficiency of data transfer between smart devices.

[0040] In an illustrative embodiment of the present disclosure, a method for activating an MCU is provided, and the method is applied to a smart device, as shown in FIG. 2. The MCU and the Wi-Fi chip are integrated in the same Wi-Fi module.

[0041] The method includes the following steps.

[0042] In step 201, a wireless message is received transmitted from the second smart device when the Wi-Fi chip is in low power mode, the wireless message being for low power mode.

[0043] At step 202, it is detected whether the wireless message is a predetermined activation message.

[0044] In step 203, if it is detected that the wireless message is a predetermined activation message, an interrupt activation signal is sent to the MCU via the activation terminal connected between the Wi-Fi chip and the MCU to activate the MCU.

[0045] Step 201 ~ step 203 is performed to activate the MCU chip in the Wi-Fi module, and after the MCU chip is activated, steps are taken to communicate with the second smart device.

[0046] At step 204, the MCU chip controls the Wi-Fi chip to switch to the normal operating mode from the low power mode.

[0047] At step 205, the MCU chip controls the Wi-Fi chip to broadcast the notification message.

[0048] At step 206, the Wi-Fi chip receives data transmitted by the second smart device in accordance with the notification message.

[0049] With embodiments of the present invention, when another smart device needs to receive or transmit data, it notifies the local Wi-Fi chip by transmitting the activation message remotely so that the Wi-Fi chip can activate the MCU via the activation pin, connected between the Wi-Fi chip and the MCU chip, and then can communicate with another smart device, thereby improving data transfer efficiency between smart devices with food.

[0050] In an illustrative embodiment of the present disclosure, a method for activating an MCU chip is provided, and the method is applied to a smart device. As shown in FIG. 3, the method includes the following steps.

[0051] In step 301, if it is detected that an event for transmitting data to the first smart device has been triggered, the second smart device generates an activation message to activate the MCU in the Wi-Fi module of the first smart device, the activation message being for the Wi-Fi chip in Wi-Fi module of the first low-power smart device.

[0052] In step 302, the second smart device transmits an activation message to the first smart device in order to activate the MCU in the Wi-Fi module of the first smart device.

[0053] In this embodiment, each of the first smart device and the second smart device can be a terminal device, such as a mobile phone, tablet, etc., and can also be an intelligent wearable device, smart home electronic equipment, etc., which is not limited in this application.

[0054] In an embodiment, after triggering a data transfer event to the first smart device, the second smart device can send an activation message to the first smart device to inform the first smart device to prepare for data transfer, regardless of whether the first smart device is in a standby state with the maximum reduction in energy consumption.

[0055] In another case, the first smart device will periodically transmit its own state to a third-party server, for example, to inform the third-party server that the Wi-Fi module of the first smart device is operational by sending messages confirming operability. If the third-party server does not receive a confirmation message sent by the first smart device in time, it can determine that the Wi-Fi module in the first smart device is in a standby state, i.e. The Wi-Fi chip is in low power mode, and the MCU chip is in standby mode with the maximum reduction in power consumption. Therefore, if the second smart device triggers a data transfer event to the first smart device, the second smart device can receive the state of the first smart device from the third party server and send an activation message to the first smart device if it is determined that the Wi-Fi module of the first smart device is in waiting state.

[0056] With embodiments of the present invention, when another smart device needs to receive or transmit data, it notifies the local Wi-Fi chip by transmitting the activation message remotely so that the Wi-Fi chip can activate the MCU via the activation pin, connected between the Wi-Fi chip and the MCU chip, thus improving the efficiency of data transfer between smart devices.

[0057] In an illustrative embodiment of the present disclosure, a method for activating an MCU chip is provided, and the method is applied to a smart device, as shown in FIG. four.

[0058] The method includes the following steps.

[0059] In step 401, if it is detected that an event for transmitting data to the first smart device has been triggered, an activation message is generated to activate the MCU in the Wi-Fi module of the first smart device, the activation message being for the Wi-Fi chip in the Wi- Fi's first smart device in low power mode.

[0060] In step 402, an activation message is transmitted to the first smart device in order to activate the MCU in the Wi-Fi module of the first smart device.

[0061] Step 401 ~ step 402 is performed to activate the MCU in the Wi-Fi module of the first smart device, if there is a need for communication with the first smart device and, starting from step 403, the communication procedure is performed after the MCU in the Wi-Fi module -Fi first smart device activated.

[0062] At step 403, a notification message is received in which the notification message is transmitted by the first smart device after the MCU in the Wi-Fi module of the first smart device is activated.

[0063] At step 404, data is transmitted to the first smart device in accordance with the notification message.

[0064] With embodiments of the present invention, when another smart device needs to receive or transmit data, it notifies the local Wi-Fi chip by transmitting the activation message remotely so that the Wi-Fi chip can activate the MCU via the activation pin, connected between the Wi-Fi chip and the MCU chip, and then establish communication with another smart device, thereby improving the efficiency of data transfer between smart devices .

[0065] In an illustrative embodiment of the present disclosure, a method is provided for activating an MCU, as shown in FIG. 5.

[0066] In this embodiment, the activation procedure of the MCU in the Wi-Fi module of the first smart device, as well as the communication procedure after activation, are described with reference to the operation procedures of both the first smart device and the second smart device.

[0067] In particular, the method includes the following steps.

[0068] In step 501, if it is detected that an event for transmitting data to the first smart device has been triggered, the second smart device generates an activation message to activate the MCU in the Wi-Fi module of the first smart device, the activation message being for the Wi-Fi chip in the module Wi-Fi is the first low-power smart device.

[0069] In particular, the predetermined message protocol for the low power consumption Wi-Fi chip is previously stored in the first smart device, and the activation message is generated in accordance with the predetermined message protocol and the rule for generating the activation message.

[0070] In step 502, an activation message is transmitted to the first smart device in order to activate the MCU in the Wi-Fi module of the first smart device.

[0071] Alternatively, the second smart device may transmit an activation message several times, since the Wi-Fi chip of the first smart device is in low power mode, and the interface for receiving a given message with low power may be unreliable.

[0072] Thus, the first smart device may not respond to the first activation message.

[0073] In step 503, the Wi-Fi chip in the Wi-Fi module of the first smart device receives a wireless message transmitted from the second smart device when the Wi-Fi chip is in low power mode in which the wireless device is designed for low power mode.

[0074] At 504, it is detected whether the wireless message is a predetermined activation message.

[0075] In particular, the activation message generation rule is pre-set in the first smart device, and it can be determined whether the received wireless message is an activation message in accordance with the generation rule, for example, by matching each field in the wireless message with the generation rule.

[0076] In step 505, if it is detected that the wireless message is a predetermined activation message, an interrupt activation signal is sent to the local MCU via the activation terminal connected between the Wi-Fi chip and the MCU in order to activate the MCU.

[0077] In an embodiment, the MCU chip and the Wi-Fi chip are integrated in the same Wi-Fi module.

[0078] The activation pin is connected between the Wi-Fi chip and the MCU chip in the Wi-Fi module, so that the Wi-Fi chip can be triggered to send a pulse signal (ie, interrupt the activation signal) to the MCU via the activation pin when the Wi-Fi chip receives an activation message.

[0079] In the present disclosure, the MCU is activated by initiating an external interrupt activation signal using an activation message from a remote smart device, thereby realizing activation of the MCU chip remotely.

[0080] In step 506, the MCU in the Wi-Fi module of the first smart device controls the Wi-Fi chip to switch to the normal operating mode from the low power mode.

[0081] In step 507, the MCU in the Wi-Fi module of the first smart device controls the Wi-Fi chip to broadcast the notification message.

[0082] In particular, the notification message can be broadcasted, so that the second smart device and other smart devices within the broadcast can be informed that the Wi-Fi module of the first smart device is already operational, and, in this way, data reception and transmission can be performed.

[0083] In step 508, the second smart device receives a notification message sent by the first smart device after the MCU in the Wi-Fi module is activated.

[0084] At this time, the second smart device determines that the Wi-Fi module in the first smart device is already operational, i.e. the MCU has been activated, and the Wi-Fi chip has already entered its normal operating state, and thus determines that the first smart device can receive and transmit data.

[0085] In step 509, the second smart device transmits data to the first smart device in accordance with the notification message.
